Der Wald ist ein wichtiger Lebensraum für Flechten und beherbergt eine Vielzahl verschiedener Arten. Dieser Kurs gibt Einblick in die Welt der Flechten in Wäldern. Auf kurzen Streifzügen in der näheren Umgebung der WSL und anhand von Kursmaterial lernen wir ausgewählte Arten kennen und bestimmen. Die Zeigerarten für authochthone Bergwälder werden vorgestellt.
1975 pflanzten die WSL und das SLF in einem gemeinsamen Projekt 92'000 Bäume am Stillberg im Dischmatal bei Davos – 2025 jährt sich diese Pflanzung zum 50. Mal
The workshop will be a forum for presenting and discussing results of research on a network of 11 Oriental beech stands across France, Germany, and Switzerland. Talks given by researchers will cover comparative analysis of European and Oriental beech regarding their phenology, growth and wood anatomy, physiology, and genetics. In particular, extensive research will be presented on the hybridization of the two species and its consequences on the long-term survival of the stands. We will also discuss if remote sensing can be used to track the spread of Oriental beech in a European beech forest. Talks given by foresters and responsible administrative bodies will cover the point of view of forestry practice and the potential for the development of a protected network of sites.
Mit diesem Kurs können die Beteiligten ihr Wissen über die Grundlagen der angewandten Naturschutzgenetik erweitern oder aktualisieren.

In recent years, the availability of Earth observation data from satellites has increased dramatically, allowing for systematic and global monitoring of Earth's surface processes at an unprecedented scale.
For several decades now, the invasive ascomycete fungus Hymenoscyphus fraxineus has caused a serious, steady population decline of common ash (Fraxinus excelsior) across Europe. This decline in ash populations in Sweden caused the species to become Red-listed in 2010, and since 2015 its status has only worsened to become critically endangered.
Flechten begegnet man auf Schritt und Tritt - vom Vorgarten bis auf die höchsten Berggipfel. Sie sind gute Indikatoren, beispielsweise zur Bestimmung der Luftgüte. Dieser Kurs gibt Einblick in die Biologie, Ökologie und die Bestimmung von Flechten. Anhand von ausgewählten Flechten werden die wichtigsten Merkmale zur Bestimmung von Flechten eingeführt. Wir werden auf Flechtenpirsch gehen, das gesammelte Material unter dem Binokular anschauen und mithilfe von Fachliteratur bestimmen.

Europe’s forests are under increasing pressure from climate extremes, requiring better monitoring of changing forest dynamics.
The upcoming *DACH Permafrost Conference* will take place at SLF Davos. This annual meeting provides an important platform to promote direct exchange between scientists working in polar and mountain permafrost regions with the aim of exploiting synergies and jointly developing methodological approaches.
Together with the rise of computational power, numerical weather prediction (NWP) models can be applied at hectometric and sub-hectometric grid spacings over mountainous terrain. Given the fine horizontal grid spacing, major topography features are resolved realistically in the model, which allows us to simulate mountain boundary layer processes such as orographically-induced gravity waves and thermally-induced flows explicitly.
Die Tabletop-Übung «Drought» verfolgt das Ziel, die Tauglichkeit des Schweizer Bevölkerungsschutzes zur Bewältigung von mehrjährigen Trockenheitsereignissen zu überprüfen. Dabei werden Mitglieder der Bevölkerungsschutz-Partnerorganisationen hypothetischen, aber realistischen extremen Dürreszenarien ausgesetzt, die vom WSL-Programm Extremes und dem Center for Security Studies der ETH Zürich entwickelt wurden. Dies ermöglicht die Überprüfung der aktuellen Strukturen, Prozesse und Ressourcen im Hinblick auf zukünftige Extremereignisse. Die Teilnahme ist nur auf Einladung möglich.
The workshop will bring together scientists and practitioners working in urban ecology and management.

Uncertainty of spillover effects (including property devaluation) from proposed land-use change elicits opposition to local development and hinders cities to implement densification land-use policy. In this context, I review how existing 3D Computer-Aided-Design (3DCAD) is used to systematically generate and evaluate building-specific design performance and how this process can be co-opted to infer a design's location-based amenity value. Connecting 3DCAD-based evaluations of building-specific visual landscape quality with financial market data, I present an integrated approach to predict the property value at risk due to newly-proposed development. Finally, I illustrate how a global assessment of the at-risk building stock allows cities and developers alike to mitigate development-associated spillover effects.
Aquatische und terrestrische Lebensräume sind eng miteinander verknüpft. Zahlreiche Pflanzen und Tierarten nutzen während ihres Lebens beide Lebensräume; zwischen «Wasser» und «Land» herrscht ein reger Austausch von Stoffen und Organismen. Auch die menschliche Nutzung und Gestaltung der Landschaft wird vom Wechselspiel zwischen aquatischen und terrestrischen Lebensräumen geprägt. Das vorliegende Buch lädt dazu ein, auf acht Exkursionen die Funktionsweise dieser Lebensräume und ihre Biodiversität aktiv zu erkunden.
The fragile landscape of hilly regions of India is susceptible to several disasters like earthquakes, landslides, snow avalanche and flash floods. Landslide disaster is one of the major recurrent concerns in Himalayan terrain. The highly sensitive hilly regions have also been subjected to enormous amount of pressure, primarily due to the escalating population thereby leading to overexploitation of natural resources. Thus, the amalgamation of ecological disruption either due to natural or anthropogenic activities is making the hill slopes fragile and thus the infrastructures unsafe. Such disasters pose risk to lives and all sorts of vital infrastructures such as human settlements, roads, rails, tunnels, hydro-power projects etc. The most recent example is the Joshimath landslidesubsidence incident which aggravated in the month of January 2023 affecting thousands of human settlements.
Vierter und letzter Infoanlass zur Feldkampagne Revision der Roten Liste der Pilze der Schweiz.
“Nature” has diverse meanings, each with its referents. Those working in environmental psychology and allied fields favor some of those meanings, using them and attending to their referents in particular ways. Other meanings see less use, despite their relevance, and their referents receive relatively little attention. I will consider some meanings of “nature” and some problems that their use or neglect has had for environment-behavior-design research. Those problems involve forms of insensitivity or blindness – to some ubiquitous and behaviorally influential natural phenomena, to historical and cultural contingencies of restorative benefits of nature experience, and to limitations of evolutionary assumptions commonly invoked in discussions of such benefits. Awareness of these problems will support further development in theory and methods useful for the study of human-nature relations.
As in all the mountains of the world, the snow, glaciers and permafrost of the European Alps are undergoing major changes in relation to the current global change. After presenting a picture of this evolution of the cryosphere, which has been accelerating since the 1990s, all the more so as the mountains are more affected by the global warming, we will show its effects on geomorphic processes such as rock fall, rock and ice avalanches, debris flows, moraine failure, or lake dynamics.
Für Forschende, die Versicherungs- und Rückversicherungsindustrie sowie für die Bundesverwaltung ist das Thema der Extremereignisse von zentralem Interesse. Dies betrifft die Vorhersage, Vorsorge und Warnung, aber auch die Anpassung und Risikominderung. Dieser vom WSL-Programm Extremes, SCOR und von der Schweizer Hagel organisierte Workshop stimulierte den Dialog zu Themen, wo es Lösungen und Fortschritte braucht, die man gemeinsam anpacken muss (z.B. Standardisierungsbedarf, Dürre-Informationstools, Schnittstelle zum Zivilschutz).
Soils are not only the basis for the production of food and other raw materials, they also store and filter water, store carbon and harbour an overwhelming biodiversity. This multifunctionality emerges from complex interactions of small scale biological, physical and chemical processes. In this presentation we discuss how such processes can be represented in a systemic soil model that allows to predict the impact of soil management and climate change on soil functions and their dynamics at the scale of landscapes.
Iva Franić (WSL) will present her work on tree seed fungi, focusing on their diversity and how they can enhance seedling vigor and resilience or threaten plant vitality.
Die Fotografien von Sam V. Furrer erkunden die zarten Details des Holzes, die Spuren seiner Bewohner sowie das Spiel von Licht und Schatten im Innern des morschen Baumstamms. Die Erläuterungen von Forschenden der WSL geben einen Einblick in eine vielfältige Welt.
The best avalanche forecasts are worth little if users are unable to understand and apply the provided information in their risk management practices. While it is well established in the risk communication community that an in-depth understanding of the needs and skills of the target audience is critical for effective communication, avalanche safety research has traditionally focused mainly on improving the accuracy of avalanche forecasts and did not pay much attention to how the information is interpreted and applied
François Munoz (Université Grenoble Alpes) will introduce a new type of eco-evolutionary modelling, based on a coalescence approach, to evaluate and test different biogeographical and evolutionary scenarios.
Leben und Forschen in der Antarktis. Matthias Jaggi erzählt von seinem Forschungsaufenthalt auf der französisch-italienischen Forschungsstation Concordia auf dem antarktischen Hochplateau.
Climate change threatens cities particularly through increasing frequency and intensity of heat waves, rainstorms and droughts. Green infrastructure is increasingly seen as a key measure for urban climate change adaptation. What potential does it really have and how should it be designed? How can the conflict between densification in growing cities and the development of green infrastructure be resolved? The lecture will present results from research projects at the Centre for Urban Ecology and Climate Adaptation at the Technical University of Munich.

Increasingly sophisticated algorithms have already become part of our lives. This development is also starting to extend to avalanche forecasting. It is starting to impact our work as forecasters and will eventually also influence our forecast products.
The operational model chain at SLF now encompasses the physical snow-cover model SNOWPACK but also recently developed machine-learning models. These models deliver predictions on various aspects relevant to regional avalanche forecasting, such as the likelihood of dry-snow or wet-snow avalanches in a region, snowpack instability, and the danger level. Taking the perspective of the avalanche forecaster, I will share examples to underscore the potential advantages and challenges associated with utilizing these models in operational avalanche forecasting at SLF.
Seismometers record signals from more than just earthquakes. Ground vibrations due to natural processes were recognized more than a century ago by scientists designing the instrumentation for earthquake detection, who mostly interpreted those signals as something polluting the seismograms, and therefore to be discarded. However, what happens if we neglect earthquakes and analyse what remains in the records?
